Ship: SAREPTA (Royal Maritime Auxiliary Service torpedo testing and research vessel)
|Port of Registry:||Admiralty, London|
Test firing was carried out from submarines, from torpedo tubes built beneath the pier of the test facility, or from a modified vessel, similar to a Clyde Puffer, equipped with two underwater torpedo tubes fitted beneath the bow. This vessel, believed to be the MV Sarepta, is said have been built in Germany and been taken from there either during, or after, World War II. When not in use, this vessel was moored off the Gamble Steps in Gourock, near the present day ferry terminal and pier.
